What is the time constant of a system with a transfer function of 1/(2s + 1)?
Step 1: Identify the transfer function given in the question, which is 1/(2s + 1).
Step 2: Look at the denominator of the transfer function, which is 2s + 1.
Step 3: Find the coefficient of 's' in the denominator. In this case, the coefficient is 2.
Step 4: The time constant (T) is calculated as the reciprocal of the coefficient of 's'. So, T = 1/2.
Step 5: Calculate 1/2, which equals 0.5 seconds. However, the time constant is often expressed in terms of the time it takes for the system to respond, which is 2 seconds.
